UNPACKING INSTRUCTIONS

ALL GANG OPERATED SWITCHES (Grounding Switch Not Included)

Each switch consists of three or more packaged items; the control parts box, the switch units, a bundle of pipe and the insulators when not assembled to the switch. Check packing list, attached to the switch crate, to determine if all material has been received. Check insulators carefully for cracked or broken por-celain. Check all other materials for possible shipment damage or loss. Report any claims to the carrier.

8.3 thru 48.3kV switch units are shipped completely assembled with insulators unless specified otherwise by the purchaser.

72.5kV thru 245kV switch units are shipped assembled, less insulators, unless specified by the purchaser or switch construction necessitates the complete assembly.

Installation instructions and print of control arrangement are packed in the control parts box in a plastic envelope. Check bill of material on control print and material received. Notify factory of any missing parts.

All switch units have been adjusted at the factory for proper contact pressure, proper opening angle, etc. and no field adjustments of the live parts are required.

Make absolutely sure applicable equipment is de-energized and properly grounded before proceeding with any installation or maintenance.

INSTALLATION, OPERATION, AND MAINTENANCEBased on IEEE Std C37.30.1-2011, Annex D

INTRODUCTION

High voltage disconnecting switches are assigned certain ratings and standard test are conducted to assure the user that the switch, when new, will perform within the ratings shown on the nameplate. It should be recognized that the switch in service will perform within these ratings only if properly operated and maintained. It cannot be stressed too strongly that prescribed safety rules should be adhered to at all times when operating or maintaining high voltage disconnecting switches near energized equipment or conductors.

MAINTENANCE

High voltage disconnecting switches are not equipped with isolating devices allowing them to be ser-viced at frequent intervals. This does not indicate, however, that care or inspection is unnecessary. The frequency of inspection will depend on the atmospheric conditions at a given location, the frequency of operation, etc., and shall be determined by the user. In noncorrosive atmospheres, a switch may oper-ate satisfactorily for many years without attention, while in a severe atmosphere such as encountered at some power plants and industrial sites, maintenance may be required in a matter of months. If it is known that a switch has carried heavy short-circuit current, special efforts should be made to inspect it at the earliest possible time, since the ability of the switch to carry rated load current or fault current may be seri-ously impaired if the contacts are not properly maintained.

Where periodic maintenance of any kind cannot be made, it should be recognized that the life of the switch may be affected. In this case, when a switch operation is made, it is suggested that the switch be opened and closed several times instead of just once in order to clean the contacts and free the moving parts more effectively. A visual inspection of a switch when wet from rain or snow might indicate hot spots which are possible sources of trouble.

The following recommendations require special consideration:

Be sure that the switch is disconnected from all electric power sources before servicing.

After power has been disconnected from the switch, ground leads to their equivalent should be attached to both sides of the switch. Such grounding may be unnecessary in the case of low voltage switches that can be visibly isolated from energized conductors by other disconnecting means.

Inspect insulators for breaks, cracks, or burns. Clean the insulators where abnormal conditions such as salt deposits, cement dust, or acid fumes prevail. This is necessary to avoid flashover as a result of the accumulation of substance on their surfaces.

Inspect contacts for alignment, pressure, burns, or corrosion. Replace pitted or badly burned contacts. If pitting is of a minor nature, smooth down the surface with clean, fine sandpaper (not emery).

Inspect interphase linkages, operating rods, levers, bearings, etc., to make sure that the adjustments have not changed or that the pipes are not bent. Check for simultaneous closing of all blades and for complete contact in the closed position. Check gearboxes for moisture, which could cause corrosion or difficulty in operating the switch due to ice formation. Inspect flexible braids or slipring commonly used for grounding the operating handle. Replace braids showing signs of corrosion, wear, or broken strands.

Inspect over-all switch for good working conditions. See that bolts, nuts, washers, cotter pins, and termi-nal connectors are in good condition. Replace items showing excessive wear or corrosion.

When a switch cannot be disconnected from power, hot stick servicing may be used as great an extent as possible.

Power-operating mechanisms attached to high voltage disconnecting switches are usually of the motor-driven, hydraulic, or pneumatic type. The maintenance instructions of the particular manufacturer of each mechanism should be followed. In addition, check limit switch adjustment, associated relay equipment for poor contacts, burned out coils, inadequate supply voltage, and any other conditions that might prevent the proper functioning of the complete switch assembly.

OPERATION

High Voltage disconnecting switches, grounding switches, and horn gap switches are given no interrupt-ing rating .* The following general rules should be followed:

Prior to operating, check to see that it is fully closed and latched or fully open, as intended.

Switches should be closed rapidly.

After operating a switch, check to see that it is fully closed and latched or fully open, as intended.

Do not use undue force in attempting to operate a switch. The operating mechanism is designed properly for the switch and any undue force, in the nature of an extension of the operating handle, an extra person on the operating handle or switch stick, may cause severe damage to the switch or mechanism. A few sharp raps on the vertical operating pipe or suddenly applied tugs on the operating handle may help to free an iced switch mechanism.

Power-operated switches should be operated periodically to ensure that the switches and their mecha-nism and control features are functioning properly. Where the circuit conditions will not permit operating the switch energized and the circuit cannot be de-energized for this purpose, it is suggested that arrange-ments be made to disengage the operating mechanism from the linkage to allow the control circuits and mechanisms to be checked, provided that this method does not adversely affect the over-all adjustment.

* It is common practice to use these devices to interrupt small values of current such as the charging current of a short length of transmission or distribution line, transformer magnetizing current, or light load current. It should be recognized that such operation results in unconfined electric arcs at the switch contacts which under unfavorable conditions may cause damage to the switch, and which may involve adjacent phase conductors or supporting structure in the initiation of system faults. Transfer switching in parallel or loop circuits also has the same attendant hazards. If current interruption is contemplated, care should be taken to be sure that the current magnitude is in a range that can be handled by the switch with a good probability of successful interruption.

DESCRIPTION The AGCH5 is an outdoor, group-operated side opening two insulator, air disconnect switch with both insulators rotating during operation. The AGCH5 is constructed primar-ily of aluminum and is available in ratings from 8.3kV through 362 kV maximum (7.5kV through 345kV nominal) and 1200 through 6000 continuous amperes. The center break is the easiest operating of all group-operated switches. Mounted horizontal upright or underhung, the blades lift no weight during operation. Mounted vertically, the blades counterbalance each other during operation.

APPLICATIONThe AGCH5 is commonly used in three-phase line or substation applications such as transformer or line disconnecting, breaker isolating, bypassing or bus sectionalizing. Operation of the AGCH5 may be accom-plished by either manual control or by motor operator.

TESTINGThe AGCH5 has been extensively tested to meet or exceed current ANSI standards. A comprehensive test brochure is available outlining electrical and mechanical design test conducted on the AGCH5.

DESIGN CHARACTERISTICS

Contacts

The AGCH5 is supplied with line-high pres-sure silver-to-silver jaw contacts producing the highest conductivity initially and over time.

The contact fingers, fabricated from hard drawn copper, are silver metallized and elec-tro-tin plated. The male contact, also of hard drawn copper, has a brazed silver overlay and is electro-tin plated. These methods and materials used in the application of the silver provide surfaces of differing hardness with anti-galling properties, resulting in minimal wear over years of operation.

All contacts on the AGCH5 are field replace-able.

The AGCH5 uses USCOs time tested welded lamination hinge assembly producing a straight-line current path eliminating any current transfer at the hinge. This is accom-plished with a welded aluminum laminated conductor that is used to create a bypass at the hinge. This eliminates the need for bolted or sliding pressure connections, or high pressure contacts, and enables ease of operation. The welded connections create a single metallic path from the hinge terminal pads to the main contacts on the blades of the switch. The laminated conductor is con-structed of commercially pure aluminum strip, which does not work harden during operation.

ACCESSORIES

Grounding switches: Through 100kA momentary Auxiliary switches: Up to 12 contact decks

are standard Standard arcing horns are installed on all

switches Outriggers: Custom designed for your application Connectors: Available on all switch types

Blade

The blade is constructed of heat-treated aluminum tubing with heat-treated aluminum castings welded to hinge and jaw ends.

Blade Mechanism

The center break design of the AGCH5 allows for better weight distribution of the blade assemblies providing excellent opera-tional performance. The center break design increases rigidity of the blades while de-creasing probability of contact misalignment, especially with higher rated switches. The two insulator configuration decrease cost while providing a simple field friendly instal-lation.

Main Switch Bearings

The AGCH5 incorporates rugged switch bearings consisting of stainless steel balls, utilizing stainless steel bearing races with galvanized ductile iron housings and rotors. The bearings are sealed at the factory for maintenance free service. Factory adjusted stops are provided with the bearing for ease of synchronization during installation. At 362kV and above the main bearing is a Timken roller bearing.

Switch Bases

Hot dipped structural steel channel is used for the construction of the switch base. Lev-eling studs are provided on the bearings for insulator alignment. Bases and base mount-ing dimensions can be customized to your specifications and structure.

Insulators

The AGCH5 is designed to accommodate commercially available insulators with three, five or seven inch bolt circle.

Operating Mechanisms

The AGCH5 may be operated with a swing handle, gearbox or motor operator. Control arrangements are factory designed and customized to your structure, with all link-age components factory cut to the required dimensions.

Hinge Current Transfer

The AGCH5 has no hinge contacts; therefore it allows current transfer with maximum reli-ability.

Transfer of current at the hinge end of the blade is accomplished with a welded alumi-num laminated conductor, precisely formed and assembled to give thousands of trouble-free operations. This eliminates bolted or sliding pressure connections, threaded jointsor high-pressure contacts, enabling ease of operation. Welded connections create a sin-gle conductive metallic path from the hinge terminal pad to the jaw end of the blade.

The laminated conductor is constructed of commercially pure aluminum strip, which does not work harden during operation. Extensive mechanical, electrical, and envi-ronmental testing along with years of field experience, prove this approach to current transfer superior to any conventional en-closed or open-hinge contact design.

DESCRIPTION The ATR is a three-insulator double center break, outdoor, air disconnect switch con-structed primarily of aluminum; available in ratings from 145kV through 550kV maximum (138kV through 500kV nominal) from 2000 to 5500 continuous amperes. This unique design incorporates triple insulator rotation for better weight distribution along with our tried and true center break blade contact assembly found on our AGCH5 unit.

APPLICATIONThe ATR is commonly used in three-phase line or substation applications such as trans-former or line disconnecting, breaker isolat-ing, bypassing or bus sectionalizing. Opera-tion of the ATR may be accomplished by either manual control or by motor operator.

TESTINGThe ATR has been extensively tested to meet or exceed current ANSI standards. A comprehensive test brochure is available outlining electrical and mechanical design test conducted on the ATR.

Contacts

The ATR is supplied with high-pressure silver-to-silver jaw contacts producing the highest conductivity initially and over time.


All contacts on the ATR are field replaceable.

The ATR uses USCOs time tested welded lamination hinge assembly producing a straight-line current path eliminating any current transfer at the hinge. This is accom-plished with a welded aluminum laminated conductor that is used to create a bypass at the hinge. This eliminates the need for bolted or sliding pressure connections, or high pressure contacts, and enables ease of operation. The welded connections create a single metallic path from the hinge termi-nal pads to the main contacts on the blades of the switch. The laminated conductor is constructed of commercially pure aluminum strip, which does not work harden during operation.

Blade


Blade Mechanism

The unique center break design of the ATR allows for better weight distribution of the blade assemblies without the need for ad-ditional phase spacing. The weight of the blades is distributed among the three insula-tors rather than all the weight balancing on the center insulator, as is the case with the double break switch. This increases rigidity of the blades while decreasing probability of contact misalignment, especially with higher rated switches.

The ATR incorporates rugged switch bear-ings consisting of stainless steel balls, utilizing stainless steel bearing races (145 - 245kV) with galvanized ductile iron housings and rotors. The bearings are sealed at the factory for maintenance free service. Factory adjusted stops are provided with the bearing for ease of synchronization during installa-tion. At 362kV and above the main bearing is a Timken roller bearing.

Switch Bases

Hot dipped structural steel channel is used for the construction of the switch base. Lev-eling studs are provided on the bearings for insulator alignment. Bases and base mount-ing dimensions can be customized to your specifications and structure.

Insulators

The ATR is designed to accommodate com-mercially available insulators with either five or seven inch bolt circle.


The ATR may be operated with a swing handle, gearbox or motor operator. Control arrangements are factory designed and customized to your structure, with all link-age components factory cut to the required dimensions.


The ATR has no hinge contacts; therefore it allows current transfer with maximum reli-ability.

DESCRIPTION The AGCH5V is an outdoor, group-operated side opening two insulator, air disconnect switch with both insulators rotating from a low profile base arrangement.The AGCH5V is constructed primarily of aluminum and is available in ratings from 15.5kV through 245kV maximum (15kV through 230kV nominal) and 1200 through 4000 continuous amperes. The V switch maintains the characteristic center break ease of operation while requiring a minimal structure footprint making it versatile for either structure or pole mounted applications. The low profile design of the AGCH5V mini-mizes structure size creating a more cost effective, aesthetically pleasing switching option. Mounted horizontal upright or under-hung, the blades lift no weight during opera-tion. Mounted vertically, the blades counter-balance each other during operation.

APPLICATIONThe AGCH5V is commonly used in three-phase line or substation applications such as transformer or line disconnecting, breaker isolating, bypassing or bus sectionalizing. The narrow mounting footprint makes the unit versatile for direct pole configurations as well. Operation of the AGCH5V may be accomplished by either manual control or by motor operator.

Contacts

The AVR is supplied with reverse loop, silver-to-silver jaw contacts producing the highest conductivity initially and over time.


All contacts on the AVR are field replaceable.

The AVR uses USCOs time tested welded lamination hinge assembly producing a straight-line current path eliminating any current transfer at the hinge. This is accom-plished with a welded aluminum laminated conductor that is used to create a bypass at the hinge. This eliminates the need for bolted or sliding pressure connections, or high pressure contacts, and enables ease of operation. The welded connections create a single metallic path from the hinge termi-nal pads to the main contacts on the blades

ACCESSORIES


standard Standard arcing horns are installed on

all group operated switches Outriggers: Custom designed for your application Connectors: Available on all switch

types

of the switch. The laminated conductor is constructed of commercially pure aluminum strip, which does not work harden during operation.

Blade


Blade Mechanism

The blade mechanism of the AVR toggles in the closed position locking the switch closed. In the open position, the blade toggles over center. Blade rotation and opening are provided by a sure and simple mechanism designed to operate in adverse conditions. The mechanism is insulated to prevent any welding during fault conditions.

The AVR incorporates rugged switch bear-ings consisting of stainless steel balls, utilizing stainless steel bearing races with galvanized ductile iron housings and rotors. The bearings are sealed at the factory for maintenance free service. Factory adjusted stops are provided with the bearing for ease of synchronization during installation.

Switch Bases

Hot dipped structural steel channel is used for the construction of the switch base. Leveling studs are provided on the bearings for insulator alignment. Bases and base mounting dimensions can be customized to your specifications and structure.

Insulators

The AVR is designed to accommodate com-mercially available insulators with three, five or seven inch bolt circle.


The AVR may be operated with a swing handle, gearbox or motor operator. Control arrangements are factory designed and customized to your structure, with all link-age components factory cut to the required dimensions.


The AVR has no hinge contacts; therefore it allows current transfer with maximum reli-ability.

DESCRIPTIONThe ASB is an outdoor, group-operated side opening two insulator, air disconnect switch with only the hinge insulator rotating during operation. The ASB is constructed primarily of aluminum and is available in ratings from 8.3kV through 72.5kV maximum (7.5kV through 69kV nominal) and 1200 through 2000 continuous amperes. The side break is the most economical of all group-operated switches.

APPLICATIONThe ASB is commonly used in three-phase line or substation applications such as transformer or line disconnecting, breaker isolating, bypassing or bus sectionalizing. Operation of the ASB may be accomplished by either manual control or by motor operator.

TESTINGThe ASB has been extensively tested to meet or exceed current ANSI standards. A comprehensive test brochure is available outlining electrical and mechanical design test conducted on the ASB.

Contacts

The ASB is supplied with reverse loop, silver-to-silver jaw contacts producing the highest conductivity initially and over time.

The contact fingers, fabricated from hard drawn copper, are silver plated, then electro-tin plated. The male contact, also of hard drawn copper is silver metallized and then electro-tin plated. These methods and materials used in the application ofthe silver provide surfaces of differing hardness with anti-galling properties, resulting in minimal wear over years of operation.

All contacts on the ASB are field replaceable.

The ASB uses USCOs time tested welded lamination hinge assembly producing a straight-line current path eliminating any current transfer at the hinge. This is accomplished with a welded aluminum laminated conductor that is used to create a bypass at the hinge. This eliminates the need for bolted or sliding pressure connections, or high pressure contacts, and enables ease of operation. The welded connections create a single metallic path from the hinge terminal pads to the main

The ASB incorporates rugged switch bearings consisting of stainless steel balls, utilizing stainless steel bearing races with galvanized ductile iron housings and rotors. The bearings are sealed at the factory for maintenance free service. Factory adjusted stops are provided with the bearing for ease of synchronization during installation.

Switch Bases

Hot dipped structural steel channel is used for the construction of the switch base. Leveling studs are provided on the bearings for insulator alignment. Bases and base mounting dimensions can be customized to your specifications and structure.

Insulators

The ASB is designed to accommodate commercially available insulators with three or five inch bolt circles.


The ASB may be operated with a swing handle, gearbox or motor operator. Control arrangements are factory designed and customized to your structure, with all link-age components factory cut to the required dimensions.


The ASB has no hinge contacts; therefore it allows current transfer with maximum reliability.

Transfer of current at the hinge end of the blade is accomplished with a welded aluminum laminated conductor, precisely formed and assembled to give thousands of trouble-free operations. This eliminates bolted or sliding pressure connections, threaded jointsor high-pressure contacts, enabling ease of operation. Welded connections create a single conductive metallic path from the hinge terminal pad to the jaw end of the blade.

The laminated conductor is constructed of commercially pure aluminum strip, which does not work harden during operation. Extensive mechanical, electrical, and environmental testing along with years of field experience, prove this approach to current transfer superior to any conventional enclosed or open-hinge contact design.

SWITCH ACCESSORIES

Auxiliary SwitchesThe addition of auxiliary switches to switch operatingmechanisms offers a means of remote switch positionindication, electrical interlocking of main and groundswitch, etc. USCO auxiliary switches are outdoor type,complete with weatherproof housing, operating crank, and control linkage. q12 Stage (6-a and 6-b)

InterlocksMechanical interlocks are used primarily for interlocking ground and main switches to prevent both switches being opened at the same time. USCO has available two types of interlocks (1) mechanical, and (2) Kirk Key.

OutriggersOutriggers are furnished when it is necessary to extend the conductors out from the switch base or other grounded parts.

Grounding SwitchesGrounding switches are supplied as an addition to themain switch, or as a separate unit. They can be installed on either the jaw or hinge end of the main switch. Grounding switches are normally interlocked with the main switch to prevent the closing of both switches at the same time.

Grounding PlatesGrounding plates are installed at the base of the structure to ground personnel while operating switches. The USCO grounding plate is available in a 48 x 36 3/16 thick galvanized steel checker plate. Consult factory for custom sizes.

Insulated ControlsA porcelain insulator can be used for insulating thevertical operating pipe. The insulator is a standard15 kV station post insulator with fittings for installing the vertical pipe.

Pole BandsUSCOs multi-purpose galvanized ductile iron, polebands (MK-678-7) are utilized for a wide variety of pole-mounted equipment. Adjustable to fit poles 6 to 24 in diameter.

Spark GapsSpark gaps provide a protective gap between live parts and ground to limit any maximum over-voltage that may occur.

INTERRUPTING DEVICES

Arcing HornsStandard arcing horns are designed to prevent arcing at the main switch contacts. Although they are given no interrupting rating, it is common practice to use these devices to interrupt small values of current such as the charging current of a short length of line or transformer magnetizing current. It should be recognized that the confined electric arc at the switch contacts could causedamage to the switch, and involve adjacent phases, or supporting structure, in the initiation of a major fault.

Vacuum InterrupterThe vacuum interrupter provides confined arc switching (in a vacuum) of load, line charging, and transformer magnetizing currents. The vacuum interrupter is capable of interrupting up to 2000 amperes at voltages 7.5kV through 230kV. At the higher voltages this interrupter utilizes vacuum units in series so interconnected that there is simultaneous separation of the contacts. Units are full voltage rated for interrupting duty up to the full continuous current rating of the main switch, with full open circuit voltage across the interrupter.

Quick Break Arcing HornsThe quick-break arcing horn is a device capable ofinterrupting a limited amount of line charging ortransformer magnetizing current. The whip action, which produces a high-speed contact separation of the stationary and moving horns, limits the length of the arc and extinguishes the arc faster than conventional arcing horns. The interrupting ability of quick break arcing horns is limited, and will vary with atmospheric and operating conditions.
